#Chemical Reaction

Datum that makes the magic between reagents happen.

Chemical reactions is a class that is instantiated and stored in a global list 'chemical_reactions_list'

Vars
H_ion_release	pH change per 1u reaction
determin_ph_range	How far out pH wil react, giving impurity place (Exponential phase)
is_cold_recipe	Set to TRUE if you want the recipe to only react when it's BELOW the required temp.
mix_message	The message shown to nearby people upon mixing, if applicable
mix_sound	The sound played upon mixing, if applicable
mob_react	Determines if a chemical reaction can occur inside a mob
optimal_ph_max	Higest value for above
optimal_ph_min	Lowest value of pH determining pH a 1 value for pH based rate reactions (Plateu phase)
optimal_temp	Upper end for above (i.e. the end of the curve section defined by temp_exponent_factor)
overheat_temp	Temperature at which reaction explodes - If any reaction is this hot, it explodes!
ph_exponent_factor	How sharp the pH exponential curve is (to the power of value)
purity_min	If purity is below 0.15, it calls OverlyImpure() too. Set to 0 to disable this.

Magical mob spawning when chemicals react

Your go to proc when you want to create new mobs from chemicals. please dont use on_reaction. Arguments:

holder - the datum that holds this reagent, be it a beaker or anything else
amount_to_spawn - how much /mob to spawn
reaction_name - what is the name of this reaction. be creative, the world is your oyster after all!
mob_class - determines if the mob will be friendly, neutral or hostile
mob_faction - used in determining targets, mobs from the same faction won't harm eachother.
random - creates random mobs. self explanatory.

REACTION PROCS Shit that happens on reaction Only procs at the START of a reaction use reaction_step() for each step of a reaction or reaction_end() when the reaction stops If reaction_flags & REACTION_INSTANT then this is the only proc that is called.

Proc where the additional magic happens. You dont want to handle mob spawning in this since there is a dedicated proc for that.client Arguments:

holder - the datum that holds this reagent, be it a beaker or anything else
created_volume - volume created when this is mixed. look at 'var/list/results'.

proc
overheated
(/datum/reagents/holder, /datum/equilibrium/equilibrium, step_volume_added)

Occurs when a reation is overheated (i.e. past it's overheatTemp) Will be called every tick in the reaction that it is overheated If you want this to be a once only proc (i.e. the reaction is stopped after) set reaction.toDelete = TRUE The above is useful if you're writing an explosion By default the parent proc will reduce the final yield slightly. If you don't want that don't add ..()

Arguments:

holder - the datum that holds this reagent, be it a beaker or anything else
equilibrium - the equilibrium datum that contains the equilibrium reaction properties and methods
step_volume_added - how much product (across all products) was added for this single step

proc
overly_impure
(/datum/reagents/holder, /datum/equilibrium/equilibrium, step_volume_added)

Occurs when a reation is too impure (i.e. it's below purity_min) Will be called every tick in the reaction that it is too impure If you want this to be a once only proc (i.e. the reaction is stopped after) set reaction.toDelete = TRUE The above is useful if you're writing an explosion By default the parent proc will reduce the purity of all reagents involved in the reaction in the beaker slightly. If you don't want that don't add ..()

Arguments:

holder - the datum that holds this reagent, be it a beaker or anything else
equilibrium - the equilibrium datum that contains the equilibrium reaction properties and methods
step_volume_added - how much product (across all products) was added for this single step

proc
reaction_clear_check
(/datum/reagent/reagent, /datum/reagents/holder)

REACTION_CLEAR handler If the reaction has the REACTION_CLEAR flag, then it will split using purity methods in the beaker instead

Arguments:

reagent - the target reagent to convert

proc
reaction_finish
(/datum/reagents/holder, /datum/equilibrium/reaction, react_vol)

Stuff that occurs at the end of a reaction. This will proc if the beaker is forced to stop and start again (say for sudden temperature changes). Only procs at the END of reaction If reaction_flags & REACTION_INSTANT then this isn't called if reaction_flags REACTION_CLEAR_IMPURE then the impurity chem is handled here, producing the result in the beaker instead of in a mob Likewise for REACTION_CLEAR_INVERSE the inverse chem is produced at the end of the reaction in the beaker You should be calling ..() if you're writing a child function of this proc otherwise purity methods won't work correctly

Proc where the additional magic happens. You dont want to handle mob spawning in this since there is a dedicated proc for that.client Arguments:

holder - the datum that holds this reagent, be it a beaker or anything else
react_volume - volume created across the whole reaction

proc
reaction_step
(/datum/reagents/holder, /datum/equilibrium/reaction, delta_t, delta_ph, step_reaction_vol)

Stuff that occurs in the middle of a reaction Only procs DURING a reaction If reaction_flags & REACTION_INSTANT then this isn't called returning END_REACTION will END the reaction

Arguments:

reaction - the equilibrium reaction holder that is reaction is processed within - use this to edit delta_t and delta
holder - the datum that holds this reagent, be it a beaker or anything else
created_volume - volume created per step
added_purity - how pure the created volume is per step

Outputs:

returning END_REACTION will end the associated reaction - flagging it for deletion and preventing any reaction in that timestep from happening. Make sure to set the vars in the holder to one that can't start it from starting up again.

proc
update_info
()

Updates information during the roundstart

This proc is mainly used by explosives but can be used anywhere else You should generally use the special reactions in /datum/chemical_reaction/randomized But for simple variable edits, like changing the temperature or adding/subtracting required reagents it is better to use this.
